Abstract
A terbium 2,6-naphthalenedisulfonic acid compound, [Tb(H2O)9]Cl(C10H6O4S4)2 (C10H6O4S42− = 2,6-naphthalenedisulfonate), is prepared and characterized by single-crystal X-ray diffraction. This compound is characterized by an isolated structure with the terbium ion possessing a mono-capped square antiprism coordination geometry. The [Tb(H2O)9]3+ cations and (2,6-naphthalenedisulfonic acid)2− anions are linked by hydrogen-bonding interactions to yield a three-dimensional supramolecular network. The solid state luminescence spectrum reveals that this compound shows the strongest emission band in the red region. The luminescence emission peaks can be ascribed to the characteristic emissions of the 4f electron intrashell transitions 5D4 → 7F5, 5D4 → 7F4 and 5D4 → 7F2 of the Tb3+ ion. The CIE (Commission Internationale de L’Eclairage) chromaticity coordinates are (0.5647, 0.4338). Solid-state UV/Vis diffuse reflectance spectra reveal that compound 1 shows a wide optical band gap of 4.92 eV.
